He smashed enemy armies in Poland, the Low Countries and Barbarossa. He won several impressive victories on the Eastern front like Smolensk '41, Minsk '41 and Kharkov '42 and the early battles of Case Blue.
He was an excellent strategist, he tried to conserve resources (supply and forces) and carefully used his forces throughout his campaigns in order to get the pot of gold at the end.
To take Moscow, von Bock needed a straight path without interruptions. The worst winter in 50 years did not help him after the conflicting orders he received nor did Hitler, (as usual) interference with the plans of the army.
Maybe it's due to the fact that he was killed without producing 'best selling' memoirs like Manstein.
